What is the specific solubilities (in g/100 g H2O) in both cold and hot water for AgCI, PbCI2, and Hg2CI2?

Answer 1

Have you tried looking in solubility tables? For example, The Handbook of Chemistry?

Answer 2

I don't have one.

Answer 3

I looked on the web and found some values for 25 C. But you need to define what is hot and what is cold. I suggest you try your library for a set of tables or ask your chemistry prof for help on finding the information. This is almost like looking for a needle in a haystack.
